GStreamer is a pipeline-based multimedia framework that links together a wide variety of media processing systems to complete complex workflows. The Kalman filter is a Bayesian filter that uses multivariate Gaussians.
This library applies a single precision, no input, constant system dynamic model Kalman filter to the pixels of the frames of a raw video stream with computation performed on CPU with an opportunity for diverse execution parallelisms.
